BUTTON-HOLE ATTACHMENT, FOR SEWING-MACHINES.

SPECIFICATION formingpart of Letters Patent No. 268,002, dated November 28, 1882,

Application filed June 16, 1879.

To all whom it may] concern:

Be it known that I, SPAULDING CUTLER, of the city of GinoinnatL-in the county of HamiL ton and State of Ohio, have invented certain I new and useful Improvements in Button-Hole Attachments for Sewing-Machines, of which the following is a specification.

Attachments for sewing and binding button-holes have heretofore been very compli- IO cated, and prominent among their defects has been the lack of machinery to properly finish the button-hole-that is, to stitch across the acute end of the hole a few times in order to furnish a neat finish, as well as strengthen the binding. This finishing is always seen in hand-made button-holes. To obviate tliese defects and shortcomings I have invented a button-hole attachment for sewing-machines,

more fully described and claimed below.

In the accompanying drawings, forming a part of this specification, Figure 1, Sheet 1, is a perspective view of my improved buttonhole attachment, taken from the rear side, or that side to which the operatingllever is secured. Fig. 2, Sheet 2, is a side elevation of the devices which give the various movements to the clamping feed-plate, and are secured to what I term the top plate of the attachment, the view being taken from the front side of the machine. Fig. 3, Sheet 2, is an end elevation of the devices shown in Fig. 2, taken from the end that appears to the right hand in said figure. Fig. 4, Sheet 2, is an enlarged sectional view taken on the line X-X,Fig. 3,

and looking from the front side of the attachment. Fig.5, Sheetfz, is a longitudinal sectional elevation of the cloth-clamping feedplafe minus the end by which it is pivoted to the base plate of the attachment. Fig. 6, Sheet 2, a

Fig. 14,,Sheet 3, is a sectional elevation on line Z Z, Fig. 13, looking toward the rear end of the attachment. Fig. 15, Sheet 3, is a detail side elevation of the means for imparting motion from the main operating-lever to the mechanism shown in Figs. 13 and 14. Fig. 16, Sheet 3, is a detail view of the adjustable link that connects the levers through which motion is imparted to the clamping feed-plate-operating pinion in the modified Fig. 17, Sheet 3, is an enlarged section taken on line U U, Fig.15. Fig. 18, Sheet 4, is a plan view of the entire attachment. Fig. 19, Sheet 4, is a longitudinal sectional elevation of the entire attachment, taken centrally through bearings of feed-plate'operating spindle, and centrally through the feedplateitself. Fig. 20, Sheet 4, is an inverted plan view of top plate of the attachment and mechanism for imparting motion to the feed-plate. Fig. 21, Sheet 5, is a plan view of the attachment with the top plate and mechanism se 0 cured thereto removed, showing bed-plate, feed-plate, and main operating-lever. Fig. 22, Sheet 5, is an enlarged transverse sectional view of the feed-plate, taken through its rack, and showing the operating-pinion in elevation. 5 Fig. 23, Sheet 5, is a sectional plan view of a modified form of t'eed-plate-operatiug mechanism. Fig. 24, Sheet 5, is a longitudinal sectional elevation of the modified form of mechanism shown in Fig. 23, taken on a line through no the bearings of the operating-spindle.

In the various figures of the drawings siinilar letters are used to designate similar parts. A is the base-plate of my attachment, and has extending from it a flat bar, A.

The supporting-plate B, for upholding and 5 maintaining in position the mechanism for laterally and obliquely shifting the feed-plate, is located above the base-plate A, (see Figs. 3, 4, 18, and 19,) and is located over that portion of said plate which is on the left hand in Fig. 1, being supported by the vertical side supports, A

The feed-plate U, with its appendages, rests upon the plate A and its extension A, being secured to said extension by the screw a, which passes through the slot a, and is screwed into said extension A at the point shown in Fig. 1. To the other extremity of the feed-plate U is attached the device for receiving the various motions to be imparted to the same. This device consists preferably of three plates screwed together, as shown in Figs. 5 and 6. The bottom plate, 24 of these three plates has. at its center a solid elevation or raised pattern, M, of the same shape as the button-hole to be sewed, as shown in Figs. 6 and 21. The second plate, a, is preferably of the same thickness as the elevation or raised pattern a of the plate a having an opening of a similar shape to that of said elevation or raised pattern, and surrounding the same,'forming a groove, 10', of equal width throughout. The third plate, a", has an opening similar in shape to the opening in the plate a, but of a larger size, and having the teeth a, as shown in Figs. 6 and 21. This third plate is placed upon the plate a in such a manner that there shall be a space between the points of the teeth of the plate a and the upper edge of the opening in plate a and so that this space shall be everywhere the same. These plates are held together and tothe feed-plate U bythe screws a". A guide-plate, V, is attached to the feed plate U by a flange, o, and extends vertically upward, having an extension,'v,which projects over the top of the plate a the object of this construction being to make the top of the guide-plate V as long. as possible and still economize room. The feed-plate U is provided with an oval slot, U, Figs. 1 and 5, between which and the guide-plate V the screw W is attached to the feed-plate U, extending vertically upward, being surrounded by a spiral 'spring,-X, on which rests the curved clampingjaw Y, which has an opening through which said screw W passes. A button-hole of proper shape having been cut in the goods, they are passed between the aforesaid feed-plate U and clamping-jaw Y, the latter being screwed down on the goods by the thumb-nut w pressing on the bearing y. The clamping-jaw Yis provided witha button-hole-shaped opening, a (see Figs. '1, 5, and.2l,) surrounding which, on the under surface of the clamping-jaw, is a downwardly-extendingflan ge, 3 which fits the opening U immediately beneath it in the feed-plate U. 'At one side of the button-hole-shaped opening y an index, 3 (see Fig.1,) is marked upon the upper surface of the clamping-jaw y, to serveas a guide to the eye in adjusting the clamping-jaw to guide the goods so as to finish a button-hole of the desired length.

The extension A of the plate A (see Fig. 1) is provided with a needle-opening, a and an opening, a, for the feed of the sewing-machine tooperate in. The opening a is always under some portion of the opening 3 of the clamping-jaw Y when the attachment is in operating condition. When the attachmentis in the position shown in Fig. 1 the needle-arm will be descending, and with the cloth in the aforesaid described position between the feed-plate U and clamping-bar Y, the work of theattaehment is accomplished by the continued descending motion of the needle-arm, forcing downward the lever-arm R,'which is attached to the inner end of a small rock-shaft supported by the standard Q, attached to the plate A. The lever-arm R, in turn acting upon aforesaid rockshaft, forces theslide T in a direction from the needle by means of the vibratingarm S, attached to the opposite end of the said rockshaft, and connected with the slide T by the connecting-rod S, the slide Toperating between the flanges a and b and-guide Q, the flange at extending upwardly from the plate A, and theone b downwardlyfrom the supportingpl'ate B, and the guide Q (see Fig. 1) extending from the foot of the standard Q under the inner edge of the guide Q, and which mesh with the teeth of the gear 02, Figs. 2 and 3, and operate the mechanism above described. The teeth t of the slide T operate the disk N, which in this direction of its motion turns loosely andinfluences no other part of the attachment. This disk N is centered upon a shaft, 111, which extends downwardly from the portion at of the disk M, (see detailed view of Fig. 9,) below the plate B, said disk being provided with the gear a, heretofore referred to. A groove, n extends diametrically across the under surface of the disk N, and has two sides, as shown in Fig. 2,0ne of which is vertical andthe other oblique, so that the disk serves as a ratchet (as the needle-bar ascends) upon the pin or vertical tooth 0 which is set in a recess in and carries with it the cylinder 0. (See Fig. 9.) It is kept constantly pressed against the under surface of the disk N by the spring 0 coiled around the stem of the vertical tooth, below the head of the latter, and compressed between said head and the bottom of the recess in which the spring is. inder 0, being pinned to shaft m by the pin 0, rotates said shaft, and by this means rotates the disk M. This disk M has also a dovetailed groove, m, in which a dovetailed piece, m slides, and is secured in positionby the tween the head and the end of the recess.

ass-.002 3 set-screw 1*, which also acts as a pin, passing through the slot Z in the lever L. ,The cylinder is prevented from retracting by the tooth P (see Fig.9) entering the vertical groove 0 and kept against the. cylinder by a spring or similar means. The rear end of this tooth P plays in a closely-fitting recess in the projection P, the shank. of the tooth playing in the rear portionof the same recess, and is there surrounded by a coiled spring compressed be- The end of the shankclosely slides in anopening in projection P, behind the recess. The cylinder has two grooves ,such as O aforesaid, diametrically opposite each other, in its curved surface. The amount of motion which the slide T receives from the levers R and Sis such as rotates the disk M exactly half-way around during the upward motion ofthe needle. A bent lever, L, is fulcrumed to the plate B at the point b One end of this .lever has a closed slot, i, into which pin l of the disk M works when said disk rotates, Figs. 1, 3, and

18, forcing the arm of the lever L in a direction from the needle, and this motion, being transmitted by the other. arm, b of said lever to the plate O, (by means of the vertical pivot 11*, projecting upwardly from the plateinto a slotin the arm,) forces the said plate (3 and its fixed appendages to slide in a limited oblique direction upon theplate B, the movement of said plate 0 being governed bythe slots cand pins 0 in a direction toward the needle and toward the slide 1. This plate 0 rests upon the supporting-plate B, the two-slots 0 being cut atan angle of about forty-five degreesxto the edges of the plate, the pins 0 being secured to the plate. B andprojecting upward through the slots 0. i i

Extending above the plate 0, and attached thereto, is the bridge 0 having a downwardly-extending sleeve, with a central orifice, through which passes and snugly fits the stem 1). (See Figs. 2, 4, and 19.) This stem D is carried by the plate 0, and its projection d extending below the gear-wheel D which is on i the lower end of the stem, fits closely in the groove n This stem D extends downward through the bridge 0 sleeve 0 box F, and sleeve ,0, hereinafter described, thelower portion of this stem D being enlarged at a point, as shown, preferablynearly midway between the top of the box F and the under side of the top of the bridge (3?, in order that the spiral spring d, which surrounds the stembetween the under side of the top of the bridge and the top of the shoulder formed by the aforesaid enlargement of the stem, may impinge against same and force the stem D9 downward, this stemD .(see Fig. 4) being retained in position by the thumb-nut d, preferably bearing ontho conical washer (i resting upon the upper side of the lever H, the stem D passingthrough the slot h (preferably oval) of said lever.

The lateral oscillation of' the feed-plate U,

by. means of which the edge and center of the slot y are alternately brought over the needlehole a is produced in the following manner: The projection 01 of the stem D, fitting in the slot a carries the feed-plate U with it in its lateral movements, the feed-plate U being pivoted at it. The stem D in its turn derives its lateral motion from the plateG, to which it is attached. Now, suppose the projection d to thest from the slide T, the movement of the plate (3 toward the slide T will carry the stem D, and consequently the plate U, in the same direction, and thus that edge of the slot 3 which is farthest from the needle-hole a will be brought toward the needle:hole,andtl1e.

thumb-nutlfl passing through the closed slot 1 in said rod in a similar direction.

The dog Gr, being pivoted in the boxfF, Fig.

7, has a point, g, adapted to impinge against the periphery of the flange E of the sleeve E,

so that when the dog is operated in this di-.

rection (see arrow, Fig. 7) it acts to revolve the sleeve-flange E'and sleeve E in a similar direction, carrying the box F with it. (See Figs. 4..and ,7.) This sleeve-flange E is attached to the upper extremity of the hollow sleeve E, which passes snugly through the downwardlyextending sleeve-axis O of the plate 0. The sleeve-axis C and its, contents ;operate through the openings bin the plate B. The sleeved flange E inay be provided with an upwardly-extending flange, e, as indicated in Fig. 7, in which case the flange would have to pass through the top of the box F. Rotatingthe sleeved flange E rotates the gear I) by means of the feather e, projecting from the interior of the sleeve E, and fitting into thever- .cular end of the slot y is brought closer to the needle-hole a at the same time that the plate 0 is moved. The plate O, when moved,swings the lever I on its fulcrum t onthe plate B by means. of. its sleeve axis 6, which passes through the slot i of said lever l. The lesser diameter of the slot i" is equal to the diameter of the sleeve -axis 0, and its larger being greater than the same, so that a lateral motion of the sleeve-axisO. will oscillate said lever I, .while a longitudinal motion will not affect it,

as, indeed, such. last-named motion cannot on account of the fulcrum i. The lever I has. a

vertical rod, J ,passing through: an orifice in be in that portion of the slot-u which. is far- IIO said lever, which .is preferably quite broad,. J

'therodbeing expandedbeneath thelever into a cross-piece,j (shown in Fig. 8,) from which two guides, j extend vertically upward. The lever 1, working upon this rod J, moves with it the lever H and its support h, (see Figs. 1, 3, and 4,) which is also attached to and supported by said lever L The upper part of the rod J is attached to the lever H by the pin [L3 in the extremity of said lever, passing through the slotj in the said rod. It is also (see Fig. 2) enveloped by a spiral spring, 7', compressed between the under surface of the lever H and a stud or shoulder on .the rod J above the lever I. The lever H, above referred to, is on the top of the bridge G (see Figs. 1, 2, and 4,) and is fulcrumed at h in the aforesaid support It. The needle-arm now descending, the needle makes astitch through the cloth a short distance from the edge of the button-hole. The lever-arm It is lowered by the descending needle-arm, and, as previously described, the disk N is rotated in a direction opposite to thatin which it last rotated. This motion does not, however, in any way affect the cylinder 0 on account of the tooth P preventing its retraction. The needle-arm now ascends and the plateG is returned to its former position, throwing the feed-plate U from the slide T, thus bringing the center of the slot 3/ toward the needle-hole or, so that the needlehole will lie just beyond the edge of the buttonhole in the goods. This motion of the plate 0 does not affect the gear D as the dog G, when retracted, loosens the hold of its point g upon the sleeve-flange'E, which, with the box, remains stationary. (See Figs. 1 and 4.) dog) is retracted to its original position in order that it may again operate the sleeve-flange E when thrown to the right by the retracting spring 0 coiled around the sleeve 0 and which extends downward to the upper surface of the box F. This spring 0 is attached to the bridge 0 and box F, and acts so as to throw the box F in a direction the reverse of the arrow, Fig. 7, when the dog G is thrownin that direction. The dog G may be stopped in its retraction by the stop-pin c in the plate 0, the spring 0 keeping the dog G against that end of the I closed slot 1 which is nearest theneedle', except when prevented from so doing by said stoppin 0 As the needle now descends it makes a stitch just over the edge of the button-hole, which, in connection with the other similar stitches, forms'the binding on the edge of the hole. The operations above described are now repeated, the stitching gradually approaching the curvedor circular end of the button hole,

around which it passes, guided by the curved portion of the groove a and then advances along the other side of the hole until the end of the hole is reached. The cam-lever'k, which is supported and journaled upon the pin k Figs. 2, 3, 4, and 19, is now elevated, and by bearing against the pin it, (to which it is connected by its fulcrum-pin passing through the slot k in the plate K, and having a head beyond the cam k to hold said cam k in posi- It (the tion against the plate K,) and being connected by said pin 70 to the vertical slide raises with it said vertical slide k which slides in the vertical groove formed by rabbets in the sides of the plate K. This vertical slide 70 is situated between the plate K and the rear vertical wall of the bridge (3 The aforesaid pin is is fastened to the plate'K at its outer side, near its lower end, said plate K being attached to the plate 0 at the end ofthe bridge 0 Fig. 4. The cam-lever k is also provided with a handle, 70 Figs. 3 andlS. The vertical slide 70 being operated upon and raised as heretofore described, forceseupone end of the lever H, which elevates the stem D, thereby withdrawing the pin d from the groove a and the teeth of the gear D from meshing with the teeth u of the plate a Elevating one end of the lever H depresses the other, forcing downward the rod J, whose notch 3' cut in the center of the vcrosspiece j Fig. 8, fits over the guide plate V, Fig. 5. As the pin d is withdrawn from the groove u and the rod J grasps the guideplate V, the feed -plate U is moved from side to side by the rod J instead of the pin d It will be remembered that the rod J is moved by the lever I, Fig. 4, and the lever I has a reciprocating lateral motion imparted to it by being fulcrumed at t, and by receiving a reciprocating lateral impulse from the stem D, Fig. 4, which latter receives a lateral reciprocating motion through the plate 0, which is reciprocated obliquely across the .length of the plate A by the arm I) of lever L, pivoted to the pivot I), located on the edge of the sliding plate 0, which in turn is kept in line by the slots 0 and guiding-pins c, as has heretofore been fully described. The gear D no longer meshing with the rack w, the feedplate U has now imparted to it a reciprocating lateral motion only. As the lateral motion of the rod J is greater than that of the pin d and as this motion is applied to the feed-plate U at a point nearer its center of vibrationviz., the screw tt--than before, the lateral motion of the feed-plate U is increased-in fact, the attachmentis preferably arranged to make this motion just twice as great as its ordinary lateral motion. The attachment now vibrating, the stitching is made transversely across the button-hole from outside to outside of the stitching previously made, thus forming the finish to the buttonhole. This capacity to finish the narrow end of the button-hole, as well as to sew the round end and sides of same, is, as has been previously mentioned, one of the objects of my invention. The rod J is depressed by raising the arm of the cam-lever7c Figs. 3 and 4, which being pivoted to the vertical slide k and hearing against the pin 70, raises the slide 70 the top of which impinges against the end of the lever H, which is on the right-hand side in Figs. 2 and 4, raises it, and the lever being fulcrumed at h, the raising of the right-hand end of said lever H depresses its other end, which in turn depresses the rod J. The spring j and the slot j are provided for the purpose I of permitting the end of the lever H to be depressed when the notch 9' is not immediately over the guide-plate V. In this case some portion of the cross-piece j rests on the guide V, and as soon as the notch j, by the continued operation of the sewing-machine, passes over the guide-plate V the spring j forces the rod J so that the notch j fits down upon and grasps the guide-plate V.

In the accompanying drawings (see Sheet 3, Figs. 13 to 1 7) a modification of my attachment is illustrated, which I will now briefly describe. Two disks, M, are provided, Fig. l7, placed beneath the plate B and connected by a crank-pin, 1. In Fig. 17 the upper disk, M,

is removed to show the connection of the crankpin 1 and slotted arm 2. Motion is imparted to either of the disks M or the disk N by the slide T, as heretofore described. The crank- .pin 1 operates the arm 2 by working in a slotted extension or yoke, 10, transverse to the length of said arm, although the said arm 2 may be well operated by being pivoted directly to the crank-pin without the intervention of a slotted extension or yoke. This arm 2 is attachedto the extension 3 of the lever I. In such a case the lever I is not i'ulcrumed at 'i, as heretofore described, but on and at the stem D. Thus the lever I operates the plate 0 and appendages, instead of the plate 0 operating the lever I. The device for rotating the stem D is changed, the stem D being provided with a gear-wheel, 4, keyed to it by a projection fitting in aslot in the edge of the stem D. This gear 4 meshes with a larger gear, 5, which is turned in one direction by a] dog, 6, similar to the dog Gr, heretofore described. This dog'is operated by means of a loop, 7, projecting from the support It. The amount of motion of the dog 6 and consequent amount of rotation of the gear 5 and stem D are regulated by the set-screw 8. As the distance between stitches depends upon the amount of rotation of stem D, this distance or len gtli ot' stitch is regulated by the set-screw 8. In the ordinary form of the attachment the length of the stitch is regulated by means of the nut l,

Fig.1, the stitch being shortened by screwing the nut I out, and the length of stitch and also its depth depend in general upon the distance of the pin 1 from the center of the u disk M, and'th'is distance is regulated by 1 motion from" the rack'T in the usual manner,

t alink, L is secured, and motion thereby through the sleeve 0 and shaft m, to'disk M and set-screw 1 The lever I is fulcrumed at t, as usual, but has a rear extension, 45 between the extremity of whichand the set-screw position.

imparted from the disk M to the lever I, the

latter in turn operating theplate O, with the mechanism thereupon, and rotating the stem D through the support It, loop 7, dog 6, and

gears 4 and5.

My attachment for making button-holes is secured preferably by a device such as the holder Z and thumb-screw A (See Figs. 11 and 12.) The holder Z consists of two upright portions or pillars united at their top by a curved arch. The lower extremity of one of these pillars is provided with a pin, 2, extending vertically downward from the center of the bot tom of said pillar, and from the lower extremity of the other pillar is ahorizon tal projection, 2, provided with a slot, 2 The mode of applying this holder is shown in Fig. 12. The" pin 2 is inserted in a recessin the plate A, and the arch of the holder overarches feed-plate U and clamping-jaw Y. When the plateUand clamping-jaw Y are moved out forsewing theround the top plate, andbecause part of myattach. ment through which the needle passes rests on the needle-plate, and because it is necessary that the other end of the attachment he elevated above the top plate the same distance that the needle'plate is, I have provided an adjustable screw, A (see Figs. 1 and 10,) having in.

its lower end a flanged base, A*. The screw A is adjusted in the plate A, so that when the base A rests onthe topplate ot the machine the end of the plate A is elevated toits proper The jam 'nut' A is now screwed down and secures the screw A in its position. This position will not have to be changed until the attachment isused on a different machine. The screw A is hollow, and through it the screw A passes loosely and screws into the top plate of the machine, securing the attachment byits pressure on the top screw, A. When the attachment is secured to the machine the arm R, Fig. 1, is attached by any appropriate means to the needle-arm and is vibrated by it.
